Description
本発明は、環境試験装置分野に関し、特に、環境試験室用蒸発器に関する。 The present invention relates to the field of environmental test equipment, and more particularly to an evaporator for an environmental test room.
環境試験室とは、技術手段を用いて自然環境を人工的に再現し、その自然環境による工業製品への破壊性の試験を行うためのものである。環境試験室による代表的な試験内容としては、高温試験、低温試験、温湿度サイクル試験などがある。上記試験を行うために、環境試験室では、主に温度や湿度を制御する。このため、環境試験室において、冷却システムや除湿システム、加湿器などが設けられる。 The environmental test room is for artificially reproducing the natural environment using technical means, and testing the destructiveness of the natural environment on industrial products. Typical test contents by the environmental test room include a high temperature test, a low temperature test, and a temperature / humidity cycle test. In order to perform the above test, the environmental test room mainly controls temperature and humidity. For this reason, a cooling system, a dehumidification system, a humidifier, etc. are provided in an environmental test room.
従来技術では、環境試験室の冷却システムにおける蒸発器は、間隔をあけて配置される複数のプレートフィンと、プレートフィンを貫通する熱交換管とからなる。従来の蒸発器は、低温時に空気乾燥装置によって除湿するしかできない。しかしながら、空気乾燥装置は除湿を行う際に、消費エネルギーが大きくて、除湿効果にも限界がある。 In the prior art, the evaporator in the environmental test room cooling system is composed of a plurality of plate fins arranged at intervals and a heat exchange tube penetrating the plate fins. Conventional evaporators can only be dehumidified by air dryers at low temperatures. However, the air dryer consumes a large amount of energy when performing dehumidification, and the dehumidifying effect is limited.
また、低温高湿度条件下において、空気中の水蒸気がプレートフィンに付着すると、蒸発器に着霜が生じて作業性を大幅に低下させてしまう。このように、従来の蒸発器において如何にして除霜するかが懸念される。従来の多くの蒸発器では、電熱素子を増設し、通電加熱により蒸発器のフィンの表面温度を昇温させてデフロストを行うことで除霜するが、このような除霜に消費エネルギーが大きい。 In addition, when water vapor in the air adheres to the plate fins under low temperature and high humidity conditions, frosting occurs in the evaporator, and workability is greatly reduced. Thus, there is concern about how to defrost in a conventional evaporator. In many conventional evaporators, an electric heating element is added and defrosting is performed by increasing the surface temperature of the fins of the evaporator by energization heating. However, energy consumption is large for such defrosting.
従って、本発明は、蒸発面を冷却、除湿させ、消費エネルギーが小さい環境試験室用蒸発器を提供することを目的とする。 Accordingly, an object of the present invention is to provide an environmental test chamber evaporator that consumes less energy by cooling and dehumidifying the evaporation surface.
上記の目的を達成するために、本発明に係る環境試験室用蒸発器は、平行に配置される複数のプレートフィンと、プレートフィンを貫通する複数の配管とを含む。各前記配管は、前記プレートフィンを貫通する直管部と、直管部の両端に連結される湾曲管部とからなるコイル状配管である。前記プレートフィンのプレート面上には、各前記配管が縦方向に沿って配置されるとともに横方向に間隔をあけて配列される。前記配管は、冷却配管と、除湿配管と、除霜配管とに分けられる。前記冷却配管及び前記除湿配管は、いずれも複数設けられる。前記除霜配管は、少なくとも1つ設けられる。前記冷却配管及び前記除湿配管は、前記プレートフィンのプレート面の横方向において、1つまたは複数ずつ交互に配列されたり、1つと複数との組み合わせで交互に配列されたりする。前記冷却配管は、冷却システムから供給される冷却剤を受ける。前記除湿配管は、除湿システムから供給される除湿冷却剤を受ける。前記除霜配管は、除湿システムの圧縮機の排気口から排気される熱気を受ける。 In order to achieve the above object, an environmental test chamber evaporator according to the present invention includes a plurality of plate fins arranged in parallel and a plurality of pipes penetrating the plate fins. Each said piping is coiled piping which consists of a straight pipe part which penetrates the said plate fin, and a curved pipe part connected with the both ends of a straight pipe part. On the plate surface of the plate fin, the pipes are arranged along the vertical direction and arranged at intervals in the horizontal direction. The said piping is divided into cooling piping, dehumidification piping, and defrost piping. A plurality of the cooling pipes and the dehumidifying pipes are provided. At least one defrosting pipe is provided. The cooling pipe and the dehumidifying pipe are alternately arranged one by one or plural in the lateral direction of the plate surface of the plate fin, or alternately arranged in combination of one and plural. The cooling pipe receives a coolant supplied from a cooling system. The dehumidifying pipe receives a dehumidifying coolant supplied from a dehumidifying system. The defrosting pipe receives hot air exhausted from the exhaust port of the compressor of the dehumidification system.
一実施形態では、前記除霜配管は、複数設けられ、前記冷却配管及び前記除湿配管と交互に配列される。 In one embodiment, a plurality of the defrosting pipes are provided, and are arranged alternately with the cooling pipes and the dehumidifying pipes.
従来の冷却システムにおける蒸発器の配管のすべてが熱交換管(すなわち、冷却配管)であることと異なり、本発明に係る環境試験室用蒸発器は、一部の配管を冷却配管として設け、他の一部の配管を除湿配管として設け、冷却配管及び除湿配管を1つまたは複数ずつ交互に配列したり、1つと複数との組み合わせで交互に配列したりすることで、冷却機能や除湿機能を兼ね備え、蒸発面を冷却、除湿させることができる。また、本発明に係る環境試験室用蒸発器では、蒸発器の配管のうちの、少なくとも1つの配管は除霜配管として機能し、除湿システムの圧縮機の排気口から排気される熱気を受け、除湿システムの圧縮機から排気すべき熱気を蒸発器に流入させて蒸発器の表面を昇温させて除霜し、その結果、低温高湿度条件下の着霜を低減させることができる。 Unlike all the pipes of the evaporator in the conventional cooling system are heat exchange pipes (that is, cooling pipes), the evaporator for an environmental test chamber according to the present invention is provided with some pipes as cooling pipes and others. Some of the pipes are provided as dehumidification pipes, and cooling and dehumidification pipes are arranged one by one or more alternately, or alternately in combination with one and more, thereby providing cooling and dehumidification functions. In addition, the evaporation surface can be cooled and dehumidified. Moreover, in the evaporator for an environmental test chamber according to the present invention, at least one of the evaporator pipes functions as a defrost pipe, receives hot air exhausted from the exhaust port of the compressor of the dehumidification system, Hot air to be exhausted from the compressor of the dehumidifying system is allowed to flow into the evaporator to raise the surface of the evaporator to defrost, and as a result, frost formation under low temperature and high humidity conditions can be reduced.
以下、添付図面を参照しながら本発明の実施形態について詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図2に示すように、冷却配管A、除湿配管B及び除霜配管Cは、プレートフィンのプレート面の横方向において、1つまたは複数ずつ交互に配列されたり、1つと複数との組み合わせで交互に配列されたりするが、具体的な配列形態に限定されない。通常、冷却配管A、除湿配管B及び除霜配管Cをより均一に分布するように、基本的な繰り返し単位で繰り返し配置することが好ましい。 As shown in FIG. 2, the cooling pipe A, the dehumidifying pipe B, and the defrosting pipe C are alternately arranged one by one or a plurality in the lateral direction of the plate surface of the plate fin, or alternately by a combination of one and a plurality. However, it is not limited to a specific arrangement form. Usually, it is preferable to repeatedly arrange the cooling pipe A, the dehumidifying pipe B, and the defrosting pipe C in basic repeating units so as to be more evenly distributed.
